Abdominal Pain and Confusion: A Case Report of Abdominal Epilepsy
(Kare Publ, 2015) Kuvandik, Guven; Karakus, Ali; Sahan, Mustafa; Ozcan, Oguzhan
Abdominal epilepsy is a recurrent and rare condition characterized by gastrointestinal symptoms such as abdominal pain, nausea, vomiting and neurological findings such as lethargy and convulsion. Although usually seen in childhood, it can also be seen in adults. After ruling out more common causes of abdominal pain, it is diagnosed with electroencephalography (EEG). The improvement of symptoms with antiepileptics is important in diagnosis. A 17-year-old woman was admitted to the emergency department with sudden loss of consciousness. On admission, general condition of the patient was moderate. The patient had confusion, and her other vital signs were as follows: Glasgow Coma Scale (GCS) at 11 (E: 2M: 5V: 4); arterial blood pressure, 100/60 mmHg; heart rate, 100 beats/min; respiration rate, 20 breaths/min and temperature, 37.2 degrees C. Other physical examination findings were normal. First serum glucose level was 85 mg/dL. Serum amylase, lipase and other laboratory test results were within normal limits. After two hours of monitoring, her consciousness was completely opened. For differential diagnosis of abdominal pain, control results were normal. There was not any abnormal findings in computed tomography (CT) scans of brain. In EEG recordings, moderately active epileptiform abnormalities were detected. Levetirasetam medication was initiated. There were no problems observed during the one-year treatment period. Abdominal epilepsy is a rare condition that should be considered in patients presented with abdominal pain and confusion. After the initial tests performed for differential diagnosis of abdominal pain, patients should be evaluated with EEG.
Ameliorating effects of tempol on methotrexate-induced liver injury in rats
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2018) Pinar, Neslihan; Kaplan, Mahir; Ozgur, Tumay; Ozcan, Oguzhan
Methotrexate (MTX) is used in the treatment of certain types of cancers and chronic inflammatory illnesses, although the clinical use of MTX is limited due to its adverse effects, the most common of which are hepatotoxicity and nephrotoxicity. In the present study, we demonstrate the protecting influence of tempol related to oxidative stress in MTX-induced liver toxicity in rats using histopathological and biochemical parameters. The rats were divided into four groups: control group (group 1), tempol group (group 2), MTX group (group 3) and MTX + tempol group (group 4). The control group (group 1) received physiological saline for 10 days; the tempol group (group 2) received 30 mg/kg i.p. for 10 days, the MTX group (group 3) received a single dose of 20 mg/kg intraperitoneal (i.p.) on the fourth day of the study, and the MTX + tempol group (group 4) received a single dose of 20 mg/kg i.p. on the fourth day, followed by tempol 30 mg/kg i.p. for 10 days. Malondialdehyde (MDA), myeloperoxidase (MPO), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were found to be significantly lower in the MTX + tempol group then in the MTX group; while superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) levels were found to be higher in the MTX + tempol group than in the MTX group. Tempol ameliorates vacuolic degeneration, inflammation and necrosis in MTX-treated rats. Our study demonstrates that tempol treatment after MTX administration ameliorates oxidative damage in liver tissue in rats.

Assessment of Ischemia Modified Albumin as a Marker of Oxidative Stress in Chronic Kidney Disease
(Wolters Kluwer Medknow Publications, 2021) Ozkurt, Sultan; Ozcan, Oguzhan; Dogan, Ibrahim
Increased oxidative stress (OS) in chronic kidney disease (CKD), and particularly in those undergoing hemodialysis (HD), is widely recognized. We aimed to evaluate ischemia modified albumin (IMA) as a marker of OS in CKD patients who are not yet on HD compared to chronic HD patients. A cross-sectional study was conducted in Hitit University, Corum, Turkey in 2015. In this study, 39 chronic HD and 36 CKD patients in stage 3-4 were included, as well as 34 healthy individuals as a control group. IMA levels in HD patients (before and after HD session), stage 3-4 CKD patients and control group were evaluated using the ELISA method. Pre-HD and post-HD albumin levels were measured and albumin-adjusted IMA (aIMA) levels were calculated. IMA and aIMA levels were higher in chronic HD and CKD patients who are not yet on HD, compared to healthy individuals (IMA, 179.76 +/- 60.46, 209.67 +/-& nbsp; 69.84, 67.41 +/- 32.22, P < 0.001, respectively, aIMA, 186.22 +/-& nbsp; 64.84, 212.96 +/-& nbsp; 72.84, 68.80 +/- ; 34.42, P < 0.001, respectively). Likewise, IMA and aIMA levels in post-HD patients were higher than pre-HD levels (IMA, 294.62 +/- 66.64, 179.76 +/-& nbsp; 60.46, P < 0.001, respectively, aIMA, 298.31 +/-& nbsp; 70.93, 186.22 & PLUSMN; 64.83, P < 0.001). Linear regression analysis identified glomerular filtration rate as the most effective factor on IMA (P < 0.001). CKD is associated with increased OS and the HD procedure itself also contributes to the increase in OS. IMA may serve as a feasible biomarker for determination of OS.& nbsp;
Association of UCMA levels in serum and synovial fluid with severity of knee osteoarthritis
(Wiley, 2019) Okuyan, Hamza Malik; Terzi, Menderes Yusuf; Ozcan, Oguzhan; Kalacı, Aydıner
Aim Osteoarthritis (OA) is one of the most common joint diseases causing physical disability in the aged population. OA pathogenesis is not fully known and yet there are no effective therapeutic options against OA. Upper Zone of Growth Plate and Cartilage Matrix Associated (UCMA) is a member of vitamin K-dependent protein family, and is involved in inflammation, cardiovascular diseases, cancer, and OA. In the present study, our aim was to detect serum and synovial fluid (SF) levels of UCMA and to analyze their correlation with radiographic findings and symptomatic severity in OA patients as well as the correlation between oxidative stress levels and SF UCMA levels. Methods Forty OA patients with cartilage degeneration and 20 patients with other knee joint disorders (non-OA control) were included in the present study. We used the Kellgren-Lawrence (KL) classification and Western Ontario McMaster University Osteoarthritis Index (WOMAC) scores to assess radiographic grading and symptomatic severity of OA, respectively. UCMA levels were measured in SF and serum. And also oxidative stress markers were analyzed in SF. Results SF UCMA levels of OA patients were higher compared to those of the non-OA control group and were positively correlated with radiographic finding and symptomatic severity of OA. However, there was no significant correlation between oxidative markers of SF and the KL grade, WOMAC scores, and SF UCMA levels in OA patients. Conclusion There is a close connection between UCMA SF levels and symptomatic and radiographic severities of knee OA. Therefore, UCMA can be a promising biomarker in the diagnosis and/or prognosis of OA disease.
Biochemical Evaluation of the Effects of Concentrated Growth Factor Liquid on Osseointegration: A Split-Mouth Design Study
(Quintessence Publishing Co Inc, 2023) Atilgan, Muhammet; Arpag, Osman Fatih; Ozcan, Oguzhan; Kacmaz, Filiz
Purpose: To investigate cytokine levels in peri-implant crevicular fluid and thus evaluate the effects of concentrated growth factor (CGF) on osseointegration. Materials and Methods: A total of 40 mandibular implants were symmetrically placed in a group of 20 systemically healthy patients enrolled in the study. In each patient, one implant wetted with liquid infiltrated from fibrin matrix was placed in the test side (Group L), and the other implant was placed in the control side without the application of any material (Group C). Peri-implant crevicular fluid was collected at 2, 4, and 12 weeks later. Marginal bone loss was measured with panoramic radiographs taken immediately after implant placement and at 12 weeks. Resonance frequency analysis (RFA) of the implants was performed intraoperatively and at 4 and 12 weeks. Results: Stability values of the implants in the CGF liquid-treated sites were higher than those of the control group at week 12 (P =.005). There was no statistically significant difference between the two groups in terms of marginal bone loss (MBL). Group L showed increased levels of tumor necrosis factor alpha (TNF-a) and receptor activator of nuclear factor kappa-B ligand (RANKL) at 2 and 4 weeks. Also, levels of osteoprotegerin (OPG) were higher in Group L at week 4 compared to Group C (P =.033). Conclusions: The increased TNF-a, RANKL, and OPG levels in this study demonstrate that CGF liquid can be used to accelerate peri-implant bone remodeling in the early phase of osseointegration.

Calcium Homeostasis During Attack and Remission in Patients With Idiopathic Benign Paroxysmal Positional Vertigo
(Lippincott Williams & Wilkins, 2016) Kahraman, Serif Samil; Ozcan, Oguzhan; Arli, Cengiz; Ustun, Ihsan; Erduran, Rana; Akoglu, Ertap; Gokce, Cumali
Objective:To evaluate changes in calcium metabolism in patients with idiopathic benign paroxysmal positional vertigo (BPPV) on initial presentation and at the follow-up visit.Subjects and Methods:The study comprised a total of 31 patients aged greater than 18 years who presented at the otorhinolaryngology outpatient clinic of our hospital, newly diagnosed as idiopathic BPPV based on the history compatible with BPPV and positive provocative maneuver (either Dix-Hallpike or Roll test). The first blood sample was obtained on the day of initial presentation when the patient was found to have active unilateral BPPV. After 6 months, a blood sample was again drawn in accordance with the procedure. Blood samples were analyzed for data on 25-hydroxyvitamin D (25(OH)-D), total calcium, parathormone and ionized calcium on initial presentation, and at the follow-up visit.Results:The patients comprised 20 (64.5%) women and 11 (35.5%) men with a mean age of 49.78 years (range, 23-75 years). During an attack a higher prevalence of decreased serum Vitamin D is less than 20ng/ml, was determined (93.5% versus 38.7%). There were statistical differences between the Vitamin D values, parathormone, and corrected by pH ionized calcium in both periods (p<0.05).Conclusion:A statistically significant association was determined between Vitamin D and calcium metabolism in patients with idiopathic BPPV. It can be considered that Vitamin D deficiency and decreased ionized Ca level may be a risk for BPPV, not only in patients with osteoporosis but also in all patients. Very low levels of 25(OH)-D seem to be associated with recurrence of BPPV. The recurrences might possibly be prevented with supplementary Vitamin D especially in those with recurrent idiopathic BPPV but further studies would be necessary to determine this.

(Dnipro State Medical Univ, 2022) Oksar, Menekse; Baytan, Hasibe G.; Turhanoglu, Selim; Aybek, Tayfun; Ardicoglu, Nazife Y.; Ozcan, Oguzhan
Tryptase test can be used as a clinical marker of mast cell activation. The present study is was aimed to identify variations in serum tryptase levels and their possible relationships with allergic reactions to protamine in low-risk patients undergoing cardiac bypass surgery. Thirty patients according to American Society of Anesthesiologists physical status III who underwent cardiac bypass surgery were enrolled. This prospective, non-randomised, clinical study was conducted in an operating room. Venous blood samples for tryptase measurements were obtained from cardiac bypass surgery patients upon admission to the operating room and immediately before and 30 min after the initiation of protamine administration. Signs of allergic reactions were recorded and management steps based on rapid effect response-based clinical assessments for diagnosis and treatment decisions during protamine administrations were described. Serum tryptase levels and clinical signs of allergic reactions, primarily mean arterial pressure (MAP), were recorded. Serum tryptase levels increased significantly and progressively during the bypass procedure (study power, 80%; sample size, 28; power of analysis, 99.8% with alpha=0.05); however, tryptase levels did not reach a sufficiently high level to confirm an allergic reaction. The MAP and heart rate decreased in 50% of the patients. Although tryptase increased significantly when compared with baseline levels, protamine-associated increases were not significant and failed to provide an unequivocal indication of an allergic response to protamine.

(Ios Press, 2020) Turk, Ayla Cagliyan; Fidan, Nurdan; Ozcan, Oguzhan; Ozkurt, Sultan; Musmul, Ahmet; Sahin, Fusun
BACKGROUND: Shoulder involvement is frequently observed in chronic renal disease (CRD) and hemodialysis patients. OBJECTIVE: Our aim is to compare shoulder Magnetic Resonance Imaging (MRI) findings of stage 4 CRD patients naive to dialysis, hemodialysis patients and healthy controls. METHODS: Twenty hemodialysis patients with shoulder pain (Group 1), 30 hemodialysis patients without shoulder pain (Group 2), 20 patients with stage 4 CRD (Group 3) and 30 healthy controls (Group 4) were enrolled. Urea, creatinine and beta 2 microglobulin were measured. Thickness, homogeneity and integrity of rotator cuff and presence of effusion were examined by MRI. RESULTS: Supraspinatus tendon was thicker in Group 1 compared to other groups, whereas infraspinatus tendon was thicker in Group 1 compared to Groups 2 and 4. Although all tendons thickness was higher in Group 3 than Group 4, there was no significant difference. Most effusion areas were present in Group 1, followed by Groups 2 and 3. There was a significant correlation between glomerular filtration rate and thickness of supraspinatus, infraspinatus tendons and between beta 2 microglobulin and thickness of infraspinatus, subscapularis tendons and total number of areas with effusion. CONCLUSIONS: Increased shoulder tendon thickness and effusion were detected in symptomatic dialysis patients, while greater effusion areas were detected in asymptomatic dialysis patients and in stage 4 CRD patients who do not require dialysis compared to healthy controls.
Correlation of serum galectin-3 level with renal volume and function in adult polycystic kidney disease
(Springer, 2019) Ozkurt, Sultan; Dogan, Ibrahim; Ozcan, Oguzhan; Fidan, Nurdan; Bozaci, Ilter; Yilmaz, Behice; Bilgin, Muzaffer
PurposeThe decrease in kidney functions in autosomal dominant polycystic kidney disease (ADPKD) is strongly correlated with the severity and growth of kidney cysts. Total kidney volume (TKV) was shown to be an early marker of the severity of the disease and a predictor of reduction in kidney functions. New treatment approaches for ADPKD have led to a need for easily applicable strong biomarkers predicting progression of the disease. The profibrotic mediator of galectin-3 (Gal-3) is linked to development of renal fibrosis.MethodsThe study included 74 patients with ADPKD diagnosis and 40 healthy controls. The TKV of patients was calculated using the manual tracing method on MR images. The serum Gal-3 levels of patient and healthy control groups were measured with the ELISA method. The correlations between serum Gal-3 value with TKV and kidney function were assessed in patients.ResultsAs the stage of chronic kidney disease (CKD) increased, serum Gal-3 and TKV values increased (p<0.001, p=0.049, respectively). Correlation analysis found a negative relationship between serum Gal-3 levels and eGFR (r: -0.515, p<0.001); however, there was no relationship between serum Gal-3 and TKV (r=0.112, p=0.344). Linear regression analysis showed the major parameter affecting Gal-3 was eGFR (p=0.016).ConclusionsIn our study, we showed that renal impairment is an important determinant of Gal-3, and there is no correlation of Gal-3 and TKV in ADPKD. As a result, there is an urgent clinical need for new biomarkers to identify individuals with the chance of treatment in the early stage among ADPKD patients.
Curcumin as a Potential Therapeutic Agent for Mitigating Carbon Monoxide Poisoning: Evidence from an Experimental Rat Study
(Int Scientific Information, Inc, 2024) Dogan, Guvenc; Kayir, Selcuk; Ayaz, Ercan; Ozcan, Oguzhan; Ekici, Arzu Akdagli
Background: Carbon monoxide (CO) is a poisonous gas and causes tissue damage through oxidative stress. We aimed to investigate the protective value of curcumin in CO poisoning. Material/Methods: Twenty-four female Spraque Dawley rats were divided into 4 subgroups: controls (n=6), curcumin group (n=6), CO group (n=6), and curcumin+CO group (n=6). The experimental group was exposed to 3 L/min of CO gas at 3000 ppm. Curcumin was administered intraperitoneally at a dosage of 50 mg/kg. Hippocampal tissues were removed and separated for biochemical and immunohistochemical analysis. Tissue malondialdehyde (MDA) levels, nitric oxide (NO) levels, and superoxide dismutase (SOD) and catalase (CAT) activities were assayed spectrophotometrically, and serum asymmetric dimethylarginine (ADMA) were measured using the ELISA technique. Tissue Bcl-2 levels were detected by the immunohistochemistry method. Results: Tissue CAT and SOD activities and NO levels were significantly lower, and MDA and serum ADMA levels were higher in the CO group than in the control group ( P <0.001). The curcumin+CO group had higher CAT activities ( P =0.007) and lower MDA than the CO group ( P <0.001) and higher ADMA levels than the control group ( P =0.023). However, there was no significant difference observed for tissue SOD activity or NO levels between these 2 groups. In the curcumin+CO group, the Bcl-2 level was higher than that in the CO group ( P =0.017). Conclusions: The positive effect of curcumin on CAT activities, together with suppression of MDA levels, has shown that curcumin may have a protective effect against CO poisoning.

(Walter De Gruyter Gmbh, 2017) Ozcan, Oguzhan; Cakirca, Gokhan; Motor, Sedat; Yonden, Zafer
Objective: We aimed to investigate the frequency of delayed notifications and probable causes of delays for critical value notification in clinical laboratory of university hospital. Materials and methods: All data was obtained from critical value reporting forms and laboratory information system. The frequency and location of critical and delayed results, latencies throughout a working day and the professional status who received the critical callbacks were shown as percentages. Results: A total of 2018 (1.02%) critical values were reported and 13.1% of them were delayed notifications. Most of them were observed in laboratory tests ordered from patients of service and polyclinics compared to ICU and emergency department (26.7%, 26%, 6.2% and 4.9%, respectively, p < 0.01). Delayed notifications were significantly higher for biochemical parameters (19.7%, p < 0.001) and observed particularly in morning hours (06: 00 a. m.-10: 00 a. m.), lunch break time (12: 00-14: 00) and end of the working day (16: 00-18: 00). Latencies of mild-delayed reporting were 18.5 +/- 4.4 min for 62.8% and advanced-delayed reporting were 47.1 +/- 11.3 min for 37.2% of total delayed notifications. Most of the critical results were reported to the health care staff other than physician (55.6%). Conclusion: Laboratory professionals should work in collaboration with responsible clinician and healthcare staff in critical value reporting process.
Designing and validating an autoverification system of biochemical test results in Hatay Mustafa Kemal University, clinical laboratory
(Croatian Soc Medical Biochemistry & Laboratory Medicine, 2022) Gul, Bahar Unlu; Ozcan, Oguzhan; Dogan, Serdar; Arpaci, Abdullah
Introduction: Autoverification (AV) is a postanalytical tool that uses algorithms to validate test results according to specified criteria. The Clinical and Laboratory Standard Institute (CLSI) document for AV of clinical laboratory test result (AUTO-10A) includes recommendations for laboratories needing guidance on implementation of AV algorithms. The aim was to design and validate the AV algorithm for biochemical tests. Materials and methods: Criteria were defined according to AUTO-10A. Three different approaches for algorithm were used as result limit checks, which are reference range, reference range +/- total allowable error, and 2nd and 98th percentile values. To validate the algorithm, 720 cases in middleware were tested. For actual cases, 3,188,095 results and 194,520 reports in laboratory information system (LIS) were evaluated using the AV system. Cohen's kappa (kappa) was calculated to determine the degree of agreement between seven independent reviewers and the AV system. Results: The AV passing rate was found between 77% and 85%. The highest rates of AV were in alanine transaminase (ALT), direct bilirubin (DBIL), and magnesium (Mg), which all had AV rates exceeding 85%. The most common reason for non-validated results was the result limit check (41%). A total of 328 reports evaluated by reviewers were compared to AV system. The statistical analysis resulted in a kappa value between 0.39 and 0.63 (P < 0.001) and an agreement rate between 79% and 88%. Conclusions: Our improved model can help laboratories design, build, and validate AV systems and be used as starting point for different test gro-ups.
Direct-acting antiviral therapy may help restore HCV-induced impaired redox balance and liver fibrosis process
(Walter De Gruyter Gmbh, 2023) Bal, Tayibe; Dogan, Serdar; Ozcan, Oguzhan; Cabalak, Mehmet; Cirkin, Berfin
Objectives: The aim of this study was to investigate the changes in thiol/disulfide balance, pro-fibrotic mediators (transforming growth factor-beta [TGF-beta] and periostin) and a potential biomarker for the prediction of HCV-induced HCC (3 beta-hydroxysterol Delta 24-reductase [DHCR24]) during direct-acting antiviral (DAA) therapy in chronic hepatitis C (CHC) patients. Methods: This prospective cohort study included 56 non-cirrhotic, treatment-naive CHC patients who were treated with DAAs between January and June 2020. Laboratory tests, including serum total/native thiol, TGF-beta, periostin, DHCR24, total bilirubin and albumin levels were measured and disulfide levels were calculated at baseline, then at 1 month and at the end of therapy (EOT). Results: Of the 56 patients, all achieved a sustained virological response after DAA therapy. There was a significant decrease in serum levels of disulfide and TGF-beta, (p=0.020 and p<0.001, respectively) and a significant increase in serum levels of native thiol compared with baseline levels (p=0.010). There was no significant change in levels of total thiol, DHCR24 and periostin levels. Serum TGF-beta levels were found to be positively correlated with total bilirubin levels (r(s)=0.470, p=0.001) and negatively with albumin levels (r(s)=-0.483, p<0.001). Asignificant moderate positive correlation was determined between baseline serum DHRC24 and disulfide levels (r(s)=0.356, p=0.007). Conclusions: The study results suggest that the DAA therapy may help to restore the impaired thiol/disulfide balance and reduce the pro-fibrotic process in CHC patients by markedly decreasing serum levels of TGF-beta, a key player in HCV-induced liver fibrosis.

The effect of Bongardia Chrysogonum on prostate tissue in a rat model of STZ-induced diabetes
(Springer International Publishing Ag, 2016) Dokuyucu, Recep; Gozukara, Kerem Han; Ozcan, Oguzhan; Sefil, Nebihat Kaplan; Nacar, Ahmet; Dokuyucu, Ahmet; Inci, Mehmet
Background: Bongardia chrysogonum is widely used in Turkey for treating urinary tract infections and prostate hypertrophy, and it also has potent hypoglycemic effects and aids glucose homeostasis. Because of the inflammatory conditions in diabetes mellitus (DM), the prostate tissue of men with diabetes is particularly susceptible to developing hypoplasia, and DM produces characteristic pathological changes in prostate tissue. Here, we examined the effects of B. chrysogonum on the prostate tissue of rats with streptozotocin (STZ)-induced diabetes. Results: The glucose levels were statistically significantly higher in the diabetic rats than in healthy controls (P < 0.001). Further, they were significantly lower in the healthy and diabetic rats administered B. chrysogonum than in the untreated diabetic rats (P < 0.001 and 0.05, respectively). The total cholesterol levels were significantly lower in the healthy rats administered B. chrysogonum than the healthy controls (P < 0.05) and diabetic rats (P < 0.01). They were also significantly lower in the diabetic rats administered B. chrysogonum than those that were left untreated (P < 0.05). The testosterone levels were significantly lower in the untreated diabetic rats than in the controls (untreated ones and those administered B. chrysogonum) and diabetic rats administered the herb (P < 0.001, 0.05 and 0.01, respectively). The oxidative stress index was significantly higher in the untreated diabetic rats than the healthy controls (P < 0.05). It was also significantly lower in the healthy and diabetic groups treated with B. chrysogonum than the untreated diabetic rats (P < 0.05). Histological examination showed no changes in the prostate tissue of the non-diabetic rats. In the diabetic group, the glandular lumens were filled with cellular debris and leucocytic infiltrate, and the glandular epithelium was degenerated and thickened. In the diabetic group treated with B. chrysogonum, the epithelium was better preserved and less debris was seen in the glandular lumen. Conclusion: To our knowledge, this is the first study to histologically prove the effects of B. chrysogonum on prostate tissue in diabetes. Our findings may be useful in developing B. chrysogonum into a therapeutic agent against diabetes and benign prostate hyperplasia.

(Springer Heidelberg, 2016) Gozukara, Ilay Ozturk; Pinar, Neslihan; Ozcan, Oguzhan; Ozgur, Tumay; Dokuyucu, Recep; Kurt, Raziye Keskin; Kucur, Suna Kabil
Purpose To investigate whether there is any therapeutic effect of colchicine on a rat model of polycystic ovary syndrome (PCOS). Methods Twenty-two Wistar-Albino rats were randomly assigned into four with 8 rats in each group: control group; PCOS only group; PCOS-metformin group and PCOS-colchicine group. PCOS was induced by gavage with letrozole once daily at the concentration of 1 mg/kg orally with 21 consecutive days. After PCOS model assessment, PCOS-metformin group was received metformin orally with 500 mg/kg and PCOS-colchicine group was received colchicine orally with 1 mg/kg for the 35 day. Histopathology of ovaries, circulating estrone (E-1), estradiol (E-2), total testosterone, androstenedione and c-reactive protein (CRP) levels were evaluated. Results: cystic and atretic follicle number was significantly decreased, but CRP and hormone parameters were not significantly changed with colchicine treatment. Conclusion Colchicine has provided histopathological improvement compared with metformin in PCOS rat model.

(Springer Heidelberg, 2017) Karapinar, Oya Soylu; Pinar, Neslihan; Ozcan, Oguzhan; Dogan, Esin Atik; Bayraktar, Suphi; Sahin, Hanifi; Dolapcioglu, Kenan
The aim of this study was to evaluate the effect of two different doses of dexpanthenol (Dxp) onexperimentally induced ovarian ischaemia/reperfusion (I/R) injury ina rat model. Forty female rats were randomly divided into fivegroups: Group 1: sham operation; Group 2: 3-h ischaemia; Groups 3: 3-h ischaemia, 3-h reperfusion (I/R); Group 4: I/R + 300 mg/kg Dxp intraperitoneally (i.p) Group 5: I /R + 500 mg/kg Dxpi.p. Total anti-oxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), tissue malondialdehyde (MDA) and activities of glutathione peroxidase and catalase were calculated. Ovarian tissue damage was assessed using a histopathological scoring system. The TOS and OSI values were significantly lower in Group 5, as compared to Groups 2 and 3 (p < 0.05). The MDA levels in Group 1 and Group 5 were significantly lower than those in Group 3 (p < 0.05). CAT and GSH-Px activity was higher in Group 5 than in Group 2 and Group 3 (p = 0.00). Tissue damage scores were elevated in all the groups compared with sham group, but the treatment with the different doses of Dxp before reperfusion ameliorated the tissue damage scores. The results showed that Dxp reduced ovarian I/R injury.
The effect of exercises on left ventricular systolic and diastolic heart function in sedentary women: Step-aerobic vs core exercises
(Elsevier Singapore Pte Ltd, 2017) Cicek, Guner; Imamoglu, Osman; Gullu, Abdullah; Celik, Oguzhan; Ozcan, Oguzhan; Gullu, Esin; Yamaner, Faruk
The purpose of this study is to investigate the effect of 16 weeks step-aerobic exercises and core exercises on left ventricular structure and function with some physiological parameters in sedentary women. Methods: To achieve the purpose of this study, a total of 45 volunteers including (step-aerobic group (SAG, n = 25), core exercise group (CEG, n = 20) were selected as participants. Two different exercises were applied for 4 days a week, throughout 16 weeks, within 60 minutes for each exercise with the intensity of heart rate (HR) 60-70 percent. The HR was measured using a heart rate monitor for each subject. The physical, biochemical and echocardiographic characteristics of the women were measured before and after the exercise. Results: During the exercise periods, there were a meaningful decrease in the body weight, BMI, value of waist region and hip circumference of the women in both intervention groups as well as in the values of HR, DBP, SBP (p < 0,05). In addition, serum homocysteine (Hcy) and high-sensitivity C-reactive protein (Hs-CRP) levels decreased and the VO2max and left ventricular diastolic end-diastolic dimension increased in both SAG and CEG (p < 0.05). The left ventricular diastolic functions of the SAG improved more than CEG. Left ventricular systolic ejection time and fractional shortening meaningfully improved in both SAG and CEG (p < 0.01). Conclusion: 16 weeks of step-aerobic and core exercise showed significant changes of inflammatory and lipid markers with cardiac dimensions and had favorable effects on both left ventricular systolic function. Left ventricular diastolic function had more improved in SAG than the CEG. (c) 2017 The Society of Chinese Scholars on Exercise Physiology and Fitness. Published by Elsevier (Singapore) Pte Ltd.

Purpose This study aims to investigate the histopathological and biochemical effects of the topical application of Hypericum perforatum on the healing of surgical wounds created in the oral mucosa of rats with experimentally induced diabetes mellitus. Materials and methods The study was carried out on 48 adult male Wistar albino rats. The animals were divided into two main groups as control and study groups. Two main groups were divided into three subgroups according to the sacrification days. All rats were given streptozotocin 60 mg/kg, after 72 hours, and those having blood glucose levels above 200 mg/dL were included in the study. Mucosal defects were created in the palatal area of the rats. H. perforatum oil was applied topically twice a day to the wounds of the rats in the study group. Animal were sacrificed on the 3rd, 7th and 10th days and samples taken from the palatal wounds were examined histologically and biochemically. Results On the 7th day, ulceration, necrosis, epithelialization, polymorphonuclear leucocytes and hydroxyproline variables showed statistically significant differences (p<0.05). Ulceration, necrosis and polymorphonuclear leukocytes values were higher in the control group, whereas epithelialization and hydroxyproline values were found to be higher in the H. perforatum group. Among 10th-day groups, there was only a statistically significant difference between the values of hydroxyproline, whereas H. perforatum-treated group showed high hydroxyproline levels (p<0.05). Conclusion Topically applied H. perforatum did not create any difference on the 3rd day, but it has positively affected the wound healing on the 7th and 10th days in diabetic rats.
